Her scheming, spoilt teenage son doesn’t agree, with jealousy soon rearing its head as Lolo – unbeknownst to his mother, of course – pulls all manner of stunts to separate these two nascent lovebirds. His practical jokes, if that’s what you’d call them, are of the highly sophisticated sort – not least planting a virus in the software Jean-René has coded for a bank, causing untold havoc.

Delpy, who co-wrote the script with Eugenie Grandval, directs with the minimum of fuss, keeping the farce fast and funny. Boon, who in France is a noted actor-director himself, plays the low-key Jean-René with aplomb, while Lacoste manages to be somewhat sympathetic, despite his insufferable behaviour. Delpy is excellent too, as the neurotic sophisticate who seems oblivious to all around her.

There’s a top cameo from Karl Lagerfeld in one particularly strange scene, when Lolo spikes Jean-René’s drink and he gets a little too friendly with the white-haired fashion guru. Like this moment, there’s much that’ll leave you smiling in Lolo, even if it never leaves a particularly long-lasting impression.

Lolo opens on November 17
